Atheist buses move in mysterious ways

The atheists' poster campaign breaks today, with the slogan "There's probably no God. Now stop worrying and enjoy your life" emblazoned on the side of urban buses across England and Wales.

I'm wholly in favour of this campaign, supported by my old friend Richard Dawkins and the British Humanist Association, among others. What a truly divine irony it is that it's the atheists and the secularists that have stumped up the money to make people in the streets think about their faith or the lack of it. The Holy Spirit using Prof Dawkins as an agent of evangelism! You couldn't make it up.

And how deliciously provocative is that "probably" in their slogan, encapsulating thousands of years of reflection on the fragile nexus that is faith. It's not a poetic line, but it's much the same sentiment that's contained in many an exilic psalm and will lead bus-travellers into the delightful meditation that is Pascal's Wager (and possibly into a conclusion that there is no direct causality between the slogan's first and second sentences).

There's more to come soon. "Famous" people will be quoted earnestly in support of atheism, such as Katherine Hepburn's epithet: "I'm an atheist, and that's it. I believe that there's nothing we can know except that we should be kind to each other and do what we can for other people."So, Katherine, might that be summarised as "Love your neighbour as yourself"?

And poet Emily Dickinson is quoted as saying "That it will never come again is what makes life so sweet". Welcome aboard the God Bus, Emily! Oh, you've reached your destination already, I see.

To appreciate how effective the atheists' ad campaign is in provoking a positive response to debate, see how little of its slogan would need to be altered as a counterpoint from the Church: "There probably is a God. Now stop worrying and enjoy your life". See?

Though it has to be said that "Be still and know that I am God" from Psalm 46 is a pithier version of the same thing. But who would read that on a bus poster from the Church? As it is, the atheists will invite hundreds of thousands of travellers to contemplate that choice.
